How do I set the timeout for the static health check of a Balancer Member of an Apache reverse proxy

Question

I am trying to configure a reverse proxy. I currently have

<Proxy balancer://myset>
    BalancerMember http://IP1:80 retry=4
    BalancerMember http://IP1:80
    Balancermember http://IP3:80
    ProxySet lbmethod=bytraffic
</Proxy>
ProxyPass "/balancer-manager" !
ProxyPass "/"  "balancer://myset/"
ProxyPassReverse "/"  "balancer://myset/"

By setting retry to 4, it lowers the time before the reverse proxy checks the health of a Member in the error state. However, if I run systemctl stop httpd (from the instance at IP1), when I refresh the balancer-manager page (of the reverse proxy), it takes a variable amount of time ( sometimes mere seconds) before it registers as Init Err. How do I configure this check to run less often? Is the check only running because I am refreshing the page? I am not using dynamic health checks, so is PING used and what's CPING, which is mentioned in the documentation? I have looked at the module page, which usually explains it exactly, but I have tried a few things, to no success. Also, if the addresses of the all BalancerMembers are pinged for every request, does that mean we have an extra 3 round trips for every request? Finally, if I decide to enable health checks (via hcheck module), does that disable the static checks? Thanks.
